Danger

Install the device TRZ04 in accordance with operating instructions. If the TRZ04
is not installed according to the manual, there is possibly an insufficient
explosion protection.

The explosion protection expires !!

Please take care during the installation to the flow direction marked on the
housing by an arrow.

When staff carry out work without sufficient qualification, risks remain
understated when working. Explosion or fire may happen. Perform the work
only if you have the appropriate qualifications and you are an expert.

If you do not use the appropriate tools and materials, components may be
damaged. Use tools that are recommended to you for the job in the operating
instructions.

Mechanical installation

Mechanical installation must only be carried out by the
respectively qualified specialist personnel.

Electrical installation

Installation on components must only be carried out by
qualified electricians.

Mechanical and/or
electrical installation

The specialist personnel require a training especially for
working in potentially explosive environment. Specialist
personnel are persons that can verify a training / further
education according to

DIN VDE 0105

,

IEC 364

or a

similar national standards

.
